Jetmoto vs Viva rear suspension

Just wondering if the Viva has this type of linkage or are using a different system.

This one is on the newest Jetmoto made by Kaier, not the older model made by Shineray.

Felt like a hardtail until it got about 100k on it then the shock loosened up and it now has around 6-7 inches of travel, just guessing, have'nt
actually tried measuring it yet.
